Dear friends!
My Somatom Plus 4 does not boot up after replace of NVRAM chip on SPARC5 board. I get an error like following: the IDPROM contents are invalid
Invalid format type (85) in NVRAM
Machine type 0xffffffff in NVRAM
Panic : No known machine types configured in!
Data Access Exception.
If I check NVRAM with printenv - command I see not any problem on it, but I cannot find any field to set machine type on NVRAM content. Any kind of help shall be much appreciated. Wish you all the best to everybody.
